Brown Paper Bag Method : Placing a turkey in a large brown paper grocery bag and cooking the bird at a very low termperature is another popular cooking method. Paper grocery bags were not intended to use as a cooking utensil, are not sanitary and may ignite causing a fire. The ink, glue and recycled materials in paper bags can emit fumes when exposed to heat. To make this method safe, replace the brown bag with a turkey-size oven-cooking bag. Follow the manufacturer’s cooking instructions and put the bag in a pan large enough so the bag does not hang over the sides. Cooking turkey at tempe ratures below 325 degrees is unsafe. When using this method, preheat the oven to 350 degrees. This method produces a moist-heat cooking environment. A thermometer can be inserted right through the plastic into the thickest part of the thigh. The turkey is done when the temperature reaches 180 degrees F.
